' s claims. (ores-wry This invention relatesyjto a device for; removing.the stack of disks: from the bowl of a: cream separator so that they.may be washed and cleaned.

In. centrifugal cream separators, the separating bowlcontains a stack.of superimposed conical rotatalole about their axes tobringthe engaging2o portionsinto or out ofengaging. position.,

tailed description which follows.

In the drawings:

Figure l is a view in. elevation ofone modifica tion .of the toolinposition inthefdisks of the cream separator bowl, the bowlfland disksbeing" I in section to show the manner ingwhich the to ol engages thedisks v 30 portions of the legs;

Figure '1 shows a. portion of ad k inf'pl'an and a leg inserted thereinin disengaged position; and

Figure 8 is the same view with the leg rotated in engaging position.

In Figure 1, there is shown acrea'ml, separator bowlbase ll] supportedon a rotatable, shaft H and. having a central tubular portion l2extending upwardly in line with the shaft. A heavy disk'l3 is mounted.on the base overthe shaft portion. Over the. heavy disk 3 a stack ofsepaw ratingdisks. I4 is located with hole s lfi therein.

These disksmust 'i Other objects will; beapparent irom-,the de Figure 2is a sectional elevation of the tool, showing the handle, the .framefand the upper from above, the cams rotate fr'ornhthe position Impositionfor effecting removal of the diskstlf'rom the separator base, a tool ordevice it is located. Thisdevice consists essentially of a pair'of rods"or legs IT, a frame land a handle i9, by means 7 of. which. the legs orrods are rotated. On the 5 end of each leg, an off-set disk-engagingportion 20 isprovided. Q I

As viewed in Figure '7, the leg is rotated to such a position that ,thedisk-engaging'porticn 20 maybe passed through the hole Hi. Inthis 10position, thelegs are inserted through the separator disks and the heavydisk, and then are rotateduntil the disk-engaging portions engage theheavy-disk; Thus, all the disks may be picked up as aunit by thetwo-legs, and transported. With; 5 the disks thus held upon the legs,they may be slid. upand, down the legs for individual inspection andnlaybe washed.

l The way in which the rotation of the handle l9 efiec'ts the rotationofthelegs it will nowbe described. The upper ends ofthe legs ll extendthrough openings 24 and have crank arm portions '22 extending at rightangles to the-main portions of the legs and in contact with the frameit. As seen in Figure Zythe handle l9,,

preferably made of wood, is keyed to ashank 25;

which" engages, the frame by means of its threaded end 25. A collar 255is located on the shankin engagement with the frame. An outer cam member2'! and an inner cam member 29 are also mounted on the shank and arefastened to-the handle by means oia screw 28.

As seen in Figures 2, 3 and 4, the outer cam member 21 consists of afiat plate with flanged edges. It is of essentially circular shapeexcept for portions 39 at opposite sides, which extend inwardly towardthe center.. The inner cam member 29, located within the outer cammember, is of similar shape, but of somewhat smaller dimensions. Thereare cut-out portions Si in the inner cammember corresponding to theportions 3!! on the outer cam'member. 7 Thus, it is. seen that a spaceis provided between the cam members in which the crank .pins 231 maytravel;- As the handle i9 is turned to theright, as viewed" shown inFigure 3 to that of Figure 4. At the start of the rotation from theposition of Figure 3, there is no rotation of the legs ll since the,crank pins travel in the portion of the space between thecammember,which'is circular.v As

the portions 3!) and, 3| come. in contact with the crank pins, 23, thecranks are rotated into line withthe shank 24. With further rotation ofthe cam members, portions 30 and tlimove past a body comprisinga frameand a pair of spaced substantially parallel rods, each mounted adja:

cent one end thereof for rotation about its own axis in the frame, saidrods at their other ends each having an elongated ofiset shoulder lughaving its greater length extending in a single radial direction withrespect to said rod, and means at said frame end of each rod to rotatethe rods to one position in which the lugs face in a direction 10 topermit insertion of the rods into the apertured articles and thereafterto rotate the rods to another position in which the lugs face in adirection to permit the lugs to engage under the aper tured elements forlifting the same.
